IMPROVED PROGRESS BAR
Field of the Invention
The present invention relates to progress bars used to measure activities with
potentially
variable speeds.
Background of the Invention
Often progress bars are used to measure the progress of a given activity. An
example of a
commonly measured activity is the progress of a download from the Internet. A
user
device, such as a set-top-box (STB) or a computer, may connect to the
internet, via an
internet connection, to download data from a remote location to a local
storage device such
as an internal hard drive or other type of memory for local use. Various
methods exist for
transferring or downloading data from one device to another. File sharing is
an example of
transferring large amounts of data across the internet. Email allows data
files to be
transferred from one user's system to another. Data can be uploaded to a
website or file
transfer protocol (FTP) server for download.
As data is received by the recipient device typically a progress meter, or
more commonly a
progress bar, is used to indicate the amount of data received. Often the
progress bar will
output this information as an indication in relation to the total amount of
data that is to be
downloaded for the particular task, although this is not always available. An
example of
such a progress bar is shown in Figure 1.
Although progress bars such as those in Figure 1 do indicate the actual
progress, to
completion, of an activity, such as a download, they do not indicate the
quality or speed of
progress. To overcome this, a numeric value is displayed on, or next to, the
progress bar
representing a real world number, such as actual download speed (e.g. in
Kb/s). However,
.. such a numeric value may not be a particularly good indication of how well
a download is
progressing, and it is questionable how useful such a number actually is to
the user.

The present inventor has appreciated that it would be advantageous to provide
an
improved progress meter, particularly one that allows a user to instantly see
the quality of
the rate of progress without needing to read or understand specific
measurements.
Summary of the Invention
The invention is defined in the claims, to which reference is now directed.
Preferred
features are defined in the dependent claims.
Embodiments of the invention provide a method for displaying the progress of
an activity
performed on a user device. The method includes outputting, to a display, a
progress
indicator indicative of the progress made in completing an activity, such as a
download,
and updating the progress indicator as the activity proceeds. Simultaneously,
a first
progress rate indicator is also output to the display, the progress rate
indicator having a
property indicative of the rate at which the activity is being progressed. The
property of the
progress rate indicator is based on a value determined by receiving a rate
value indicative
of the activity progress rate and comparing the rate value with a value
indicative of the
maximum progress rate of the user device for the particular activity.
The progress rate indicator is preferably a displayed item having a visual
appearance
indicative of the portion of the rate at which the activity is being completed
compared to a
maximum value. In other words, the progress rate indicator indicates progress
rate relative
to a maximum rate.
The progress rate indicator is, preferably, updated throughout the course of
the activity
being performed, to indicate the change in rate of performance. To achieve
this the
method may further include the step of displaying one or more further updated
progress
rate indicators, subsequent to displaying the first progress rate indicator.
Subsequent
progress rate indicators preferably replace the previous rate indicators to
avoid confusion.
Embodiments of the invention can be applied to any activity that has a
variable speed. A
progress indicator, such as a progress bar, is displayed, but rather than
displaying a simple
monochrome, or fixed colour, bar the bar itself is coloured to represent the
speed at which
the activity is being completed. Different colours are dynamically used to
represent
different progress rates.

The absolute measure of progress provided by the progress bar can be static,
based on
typical, estimated, or previously measured system performance. Alternatively
it can be
dynamically ranged against the maximum progress rate of the current activity,
in which
case the maximum progress rate value is preferably updated as a higher rate
value than
the previous highest rate value is received. The progress bar is then
dynamically
coloured depending on the ongoing current progress rate.
Preferably, as mentioned above, the progress rate is indicated by visual means
such as
a plurality of colours or patterns. Preferably a first colour is used to
indicate a minimum
progress rate and a second colour to indicate a maximum progress rate. The
progress
rate indicator colour may vary continuously between the first colour and the
second
colour in response to the received rate value. Alternatively, the progress
rate range
may be divided into discrete steps, and a different colour used to indicate
each step.
Preferably, the progress rate indicators are overlaid on the progress
indicator. That is,
the progress rate indicators are displayed such that they appear in front of
the progress
indicator so as to be clearly visible over the progress indicator. The
progress indicator
and the progress rate indicator may be integral, in that they are both
contained within
the same display item. The progress rate indicator may be a visual property of
at least
a portion of the progress indicator.
A corresponding user device may be provided, the user device being configured
to
undertake any of the method steps described above and below, to output a
progress
indicator and progress rate indicator to a display. The user device may take
the form of
a set top box, or may be incorporated into a set top box. A computer program
may also
be provided for carrying out the method steps described above or below on a
suitable
user device.

Detailed Description of the Preferred Embodiments
Embodiments of the invention will be described primarily with reference to the
activity of
downloading data from the internet, or other data source such as a device on a
local
network. It will be appreciated that embodiments of the invention can be
applied to the
monitoring of any activity in which the progress to completion has a variable,
or potentially
variable, rate.
Figure 2 shows a progress indicator in accordance with an embodiment of the
invention.
The progress indicator is in the form of a progress bar 201, being a
rectangular shape, a
portion of which is changed visually from the remainder of the shape to
indicate the
progress of the download. The proportion of the bar that is visually changed
indicates the
proportion of the download activity that has been completed. Typically the
visual change is
a change in colour of the portion of the bar relative to the starting colour
of the bar. Value
indicators are provided indicating the percentage of the download that has
been completed,
but this is not required.
As shown in Figure 2, the progress bar shows a certain portion of the download
activity is
complete by colouring section 202 a different colour to the remainder of the
bar. However,
rather than the colour of the complete portion 202 remaining static throughout
the
CA 02777200 2012-05-16
download activity, it is varied dependent upon the download rate. This is
shown in Figures
3 and 4 in which the download has progressed, but the rate of download has
also changed
from the first rate of Figure 2 to a second and third rate in Figures 3 and 4
respectively.
The colour of portion 202 is the progress rate indicator, indicative of the
current download
5 rate in relation to the maximum download rate of the user device on which
the progress bar
is running. Therefore, rather than giving the user a value indicative of the
actual current
download rate a value indicative of how good the performance is in comparison
to
expected or possible performance is provided. Figure 5 illustrates the general
method
involved. At step 501 the progress of the download is determined. This can be
achieved in
a known way by, for example, determining the amount of data that has been
downloaded to
the user device and comparing this with the total amount of data to be
received. The
progress of the download may then be output to the user in the progress
indicator, such as
the progress bar shown in Figure 2. Simultaneously, at steps 503 to 505, the
progress rate
indicator value or setting to be represented by the progress rate indicator is
determined and
output to the user in the form of the progress rate indicator. In particular,
at step 503 a rate
value indicative of the download rate is determined; this may be determined in
a standard
way as would be known to the skilled person. At step 504 the download rate is
compared
with the maximum progress rate of the user device do give the value to be
represented by
the progress rate indicator. Preferably this is achieved by determining the
ratio or
proportion of the actual download rate to the maximum download rate. The
progress rate
indicator value is then output to the user in the form of the progress rate
indicator. The
steps 501-502 and 503-505 may be performed independently of one another. The
steps
501-502 and 503-505 may be performed continuously throughout the download at
the
same or at different rates such that the progress rate indicator is updated
less frequently,_
more frequently, or as frequently as the progress indicator.
As an example of the method of Figure 5, the user device may determine that
the
download has progressed to 40% completion. At the same time, the user device
determines, or receives data indicating, that the download rate or speed is
200 KB/s. This
is compared to the maximum download rate of the user device which is 1 MB/s.
Therefore,
the user device determines that the download rate is 1/5th the maximum value.
The
progress rate indicator is set to indicate this performance and output to the
user.
Embodiments of the invention may set the maximum download rate of the user
device
based on one of two exemplary methods. Firstly, as illustrated in Figure 6,
the absolute
maximum download rate of the user device is determined at step 601. By this,
it is meant
CA 02777200 2012-05-16
6
that the absolute maximum rate that the user device hardware is capable of is
determined,
this being a static value. This can be achieved by using a maximum value based
on typical
or previously measured system performance, such as performing appropriate
tests on the
hardware. For example, it may be determined that the user device is capable of
downloading, from an appropriate source, at a rate of 2 MB/s. At step 602 the
current, or
instantaneous, download rate of the present download activity is determined.
The present
download rate and maximum download rate are then compared at step 603 to
determine
the proportion of the current download rate in relation to the maximum
download rate. The
progress rate indicator is then set, at step 604, to display a value
indicative of the present
download rate relative to the maximum download rate. For example, the present
download
rate may be determined to be 0.5 MB/s, and the progress rate indicator is
therefore set to
display a value or indication that the download rate is 25%, or 1/4 of the
maximum download
rate.
A second manner of setting the maximum download rate of the user device is
illustrated in
Figure 7. At step 704 the relative maximum download rate of the user device is
determined. By this, it is meant that the maximum download rate that the user
device has
achieved over a predetermined period is determined, and taken to be the
maximum
download speed. The predetermined period may be the period for which the user
device
has been operational, or it may be, for example, the period for which the
download has
been occurring. Once the maximum download rate value has been determined, the
method proceeds in a similar manner to that discussed in relation to Figure 6,
with the
actual current download rate being determined at step 702 and a comparison
being
performed between the actual download rate and the maximum download rate at
step 703.
This allows the user device to determine the current download rate relative to
the maximum
download rate, allowing the progress rate indicator to be set to a value
relative to the
maximum download rate, at step 704, and thus give an indication of the
quality/speed of
the current download rate relative to the maximum download rate. In addition,
the method
may optionally include the step of continuously, or periodically, determining
the relative
maximum and setting the maximum download rate to the highest determined value.
In this
way, the maximum download rate is dynamically ranged against the maximum
download
rate of the desired period of time, such as the current download. For example,
the fastest
rate the current download has gone to the current point in time may be 200
KB/s, but the
absolute maximum may be 2MB/s. 200 KB/s becomes the maximum download rate
until,
at some point in the future of the current download, the rate increases to 500
KB/s, at
which point this value is set as the maximum. The actual download rate is
continuously or
CA 02777200 2012-05-16
7
periodically monitored and the progress rate indicator is set accordingly,
depending on the
current download rate and current maximum download rate.
The progress rate indicator indicates the rate at which the current activity,
a download in
this case, is proceeding. In conjunction with the progress indicator the user
is informed of
how far the download has progressed, and at what rate, relative to the maximum
possible
rate, the download is proceeding. This means that the user has an indication
as to how
well their system is performing in the activity.
The progress rate indicator may take the form of any suitable visual
indicator, and may, in
some embodiments, be a number or value varied between a minimum and maximum
value, the maximum value being the maximum download rate. However, in a
preferred
embodiment the progress rate indicator is dynamically coloured depending on
the ongoing
download speed. In particular, the colour may change between a first colour
and a second
colour in response to the download rate. The first colour may represent a
minimum rate,
with the second colour representing a maximum rate. The colour may change
between
these two colours, or further colours may also be provided between the maximum
and
minimum colours, to indicate the download rate value relative to the maximum.
As an example, the colour red may be used to indicate a minimum speed of
OKB/s, and
the colour green may be used to represent a maximum speed of 1MB/s (either
because
this is the absolute maximum or the relative maximum as described above). If a
user is
downloading a file, such as a movie, from the internet and the speed of
download
continues at 1MB/s, then the progress rate indicator will be coloured green,
indicating the
highest download rate relative to the maximum. If the download speed starts to
slow down,
the colour of the progress rate indicator starts to change in response. If the
speed drops to
750 KB/s, the indicator may change to a green/yellow mix, at 500 KB/s yellow,
at 250 KB/s
a red/yellow mix and at or close to OKB/s red, or almost completely red. Of
course this is
just an example, and different colours may be used.
The colour change of the progress rate indicator in response to the download
rate changes
can be implemented as a smooth mixing. In this way, the colour of the progress
rate
indicator varies continuously between the minimum and maximum colours (and any
intervening colours), the mix of colours being interpolated across the whole
of the
download spectrum such that the progress rate indicator would gradually change
colour
between, for example, green and red. The ratio of one colour to another in the
colour
mixture is dependent upon the download rate and the maximum download rate.
CA 02777200 2012-05-16
8
Alternatively, the colour change of the progress rate indicator in response to
download rate
changes may be divided into discrete steps. A predetermined number of discrete
colours
are used, each one representing a predetermined range of download speeds in
relation to
the maximum value. For example, red may represent a download rate of 0-25% of
maximum, orange 25%-50%, yellow 50%-75% and green 75%-100%.
Colours are preferable to represent the download rate since they can be
understood
intuitively without needing to understand any displayed numbers or know the
maximum
download rate of the system. Of course other visual indicators could be used
for the
progress rate indicator, such as patterns, with a pattern of crosses
indicating a poor rate,
.. dots a good rate and stripes an intermediate rate. Alternatively the
absence of a colour or
pattern may indicate a good rate, with the indicator becoming coloured or
patterned to a
greater degree as the download rate decreases (or vice versa).
In other embodiments the progress rate indicator may be a simple figure scaled
from, for
example, 0-10, with 10 being a maximum rate and 0 being the minimum rate. Of
course,
any suitable minimum and maximum values may be used for display.
Although the progress indicator and the progress rate indicator may be
separate items,
displayed simultaneously but in separate portions of the screen, it is
strongly preferred that
the progress rate indicator is overlaid on the progress indicator. This may be
achieved by
making the progress rate indicator and the progress indicator integral with
one another, and
particularly with the progress rate indicator being a visual property of the
progress indicator.
This is illustrated in Figures 2-4. The progress indicator is in the form of a
progress bar
201. As the download progresses the bar is filled in with a portion 202 having
a different
visual appearance, such as a different shading or colour, to the rest of the
bar. Because
this portion is visible on the progress indicator it can be consider
"overlaid" on the progress
indicator. The amount of the bar that is coloured indicates the amount of the
download that
has completed as described above. The colour of this portion may, according to
embodiments of the invention, be used as the progress rate indicator as
discussed above.
As shown in Figure 3, the rate of download changes, resulting in the progress
rate indicator
302 changing colour from that displayed in Figure 2. Likewise, the rate
changes again to
Figure 4.
Other arrangements are possible, such as the progress rate indicator being a
fixed size
shape of varying colour. Alternatively, the progress rate indicator may be
represented in
CA 02777200 2012-05-16
9
the unfilled portion of the progress bar, with this portion changing colour,
the portion that is
filled to indicate progress being a fixed colour.
Although a rate bar has been described as the preferred format for the
progress indicator, it
will be appreciated that other forms for the progress indicator could be used.
For example,
the progress indicator could be annular.
The rate of download represented by the progress rate indicator is preferably
the
instantaneous download rate or the average download rate over a particular
recent period.
The user device may continuously receive the rate information such that the
displayed rate
indicator is continuously updated, or it may be done periodically, such as,
for example,
every 5-10 seconds.
Embodiments of the invention may include a user device configured to perform
the
methods described above. Such a user device may include an input for
downloaded data,
an input for receiving current download rate data and an input for receiving
data indicative
of the maximum download rate. Alternatively, the user device may be configured
to
determine the current and maximum download rates using an internal processor,
based on
the received downloaded data and/or the user device specifications. The user
device also
includes an output for outputting the progress indicator and progress rate
indicator to a
display such as a screen or television. A processor or CPU is provided for
comparing the
rate value with a value indicative of the maximum progress rate/download rate
so as to
determine the correct parameter to apply to the progress rate indicator for
display to the
user.
Embodiments of the invention find particular utility in user devices such as
set-top-boxes
for receiving and encoding media content for display, computers, mobile
phones, PDAs,
tablets and any other user device that may need to display a progress bar for
an activity
having a variable rate, such as internet downloads.
Although examples have been described in relation to downloading content or
data, the
invention may be applied to any activity with a variable rate, such as
uploads, progress
through a television show or film (with different fast forward/rewind rates
being available to
the user) and so forth.
CA 02777200 2012-05-16
For the avoidance of doubt, the invention may be embodied in a computer
program
arranged to carry out any of the methods discussed herein on a suitable
computer or any
suitable user device, particularly a STB.
